Abstract: A fastener joining an object to a panel includes a fastener plate nonrotatably receiving the object. Elastically displaceable elements, each having multiple concave shaped detents alternately engage a panel mounting aperture when the displaceable elements are inserted into the mounting aperture. Multiple retention positions are provided by the multiple detents.

Abstract: A resilient clip having an engagement tab, which terminates at a load distributing element, and wing members that are configured to co-engage a structure to which the resilient clip is to be coupled. The wing members terminate at an engagement edge and are configured to co-engage the structure at a location along a length of their engagement edge. The load distributing element being configured to contact the structure in response to application of a withdrawing force to the resilient clip so that the load distributing element increases an area over which the withdrawing force.
